Tire pressure balance apparatus

ABSTRACT

A tire pressure balance apparatus for balancing a left tire with a right tire of a car is proposed. The tire pressure balance apparatus comprises: a first air pumping head for connecting to the left tire; a second air pumping head for connecting to the right tire and stopping an air of the left tire before connecting to the right tire; and a pipe having two sides, the one side connecting to the first air pumping head and the another side connecting to the second air pumping head, a pressure of the left tire and the right tire being balanced after the first air pumping head being connected to the left tire and the second air pumping head being connected to the right tire.

FIELD OF THE INVENTION

[0001] The present invention is related to a tire pressure balanceapparatus, and more particularly to the apparatus for balancing a lefttire and a right tire of a car.

BACKGROUND OF THE INVENTION

[0002] All drivers know that the impact of tire pressure on the carperformance is very serious. A car will spend a lot of gas in case ofless tire pressure. On the contrary, it will decrease the roadholdingand easily make blowout in case of more tire pressure. Therefore, onewill check the tire pressure during the car maintenance. Generally, thetire pressure index is between 26 and 35. As long as the tire pressureis located in this range, the tire should be normal. A tire pressuremeter will be used to check the tire pressure of four tires of a car. Ifthe tire pressure is less, one can pump the tire. If the tire pressureis more, one can deflate it. The tire pressure of the front tires isdifferent from that of the back tires. But, the tire pressure of theleft tires and the right tires must be the same. If the tire pressure ofthe left tires and the right tires is not the same, the steering wheelmay be not regular and the car performance will be down. For example,the speedup, the turning and the car stopping will become worse.

[0003] The conventional tire pressure meter is always finger-wise. Whenthe tire pressure is measured, one can get an approximate value. But,there must have an error between the measured value and the practicalvalue. For example, the measured value may be 30, but the practicalvalue may be 29.5 or 30.1. The error is always ignored at themeasurement procedure, but it will impact on the driving safety verymuch.

SUMMARY OF THE INVENTION

[0004] An object of the present invention is to provide a tire pressurebalance apparatus for balancing the left tire with the right tire of acar.

[0005] Another object of the present invention is to provide a tirepressure balance apparatus for promoting the driving safety.

[0006] According to the present invention, a tire pressure balanceapparatus for balancing a left tire with a right tire of a car, the tirepressure balance apparatus comprising: a first air pumping head forconnecting to the left tire; a second air pumping head for connecting tothe right tire and stopping an air of the left tire before connecting tothe right tire; and a pipe having two sides, the one side connecting tothe first air pumping head and the another side connecting to the secondair pumping head, a pressure of the left tire and the right tire beingbalanced after the first air pumping head being connected to the lefttire and the second air pumping head being connected to the right tire.

[0007] In accordance with one aspect of the present invention, the firstair pumping head is pinch-wise.

[0008] In accordance with one aspect of the present invention, thesecond air pumping head is press-wise.

[0009] In accordance with one aspect of the present invention, the pipeis a plastic pipe.

[0010] In accordance with one aspect of the present invention, the pipehas a air pumping hole.

[0011] The present invention may best be understood through thefollowing description with reference to the accompanying drawings, inwhich:

BRIEF DESCRIPTION OF THE DRAWINGS

[0012]FIG. 1 is an illustration of a tire pressure apparatus accordingto the present invention;

[0013]FIG. 2 is an application illustration of the tire pressureapparatus according to the present invention; and

[0014]FIG. 3 is an another illustration of the tire pressure apparatus.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0015] Please refer to FIG. 1 showing the illustration of the tirepressure apparatus. The tire pressure balance apparatus 10 consists ofthe pinch-wise air pumping head 14, the plastic pipe 12 and thepress-wise air pumping head 13. And, the pinch-wise air pumping head 14includes a spanner 11. During operation, one can use the spanner 11 tofix the pinch-wise air pumping head 14 on the pumping hole of the lefttire. Next, put the press-wise air pumping head 13 on the pumping holeof the right tire, and press it. Thus, the air in the left tire willpass to the right tire through the tire pressure balance apparatus 10.Therefore, the target of balancing the left tire with the right tirewill be attained.

[0016]FIG. 2 shows the application illustration according to the presentinvention. After the left tire 21 and the right tire 22 of the car ispumped, one can use the tire pressure balance apparatus 10 to balancethe tire pressure. The pinch-wise air pumping head 13 may be pinched onthe pumping hole of the left tire 21, when the press-wise air pumpinghead 13 will hinder air from the left tire, then the press-wise airpumping head 13 may be press onto the air pumping hole of the right tire22. Thus, the air of two tires will be passed each other, so the tirepressure of two tires will be balanced naturally.

[0017]FIG. 3 shows another tire pressure balance apparatus 30. There isa air pumping hole 31 adding to the plastic pipe. One can use this airpumping hole 31 to pump air to the left tire and the right tiresimultaneously. Thus, the tire pressure of the left tire and the righttire will be the same after pumping. In this case, the two air pumpinghead should use the pinch-wise air pumping head. Certainly, the airpumping hole 31 may also use a quick coupler. Thus the user can connectto another quick coupler on an air compressor for quickly pumping air.Certainly, the tire pressure balance apparatus may add a pressure meteron the pipe to measure the tire pressure of two tires simultaneously.Secondly, the tire pressure balance apparatus may directly install onthe air pump for simultaneously pumping two tires. Even the plastic pipecan modified as four plastic pipes that pass each other. Thus, the tirepressure balance apparatus can used to balance four tires for some largesize cars. The pipe; may be a soft pipe, but it may be a hard pipe ifneed. The air pumping head may both be pinch-wise, or both bepress-wise. The advantages according to the present invention are asfollows:

[0018] 1. The production cost is low, because the elements of the tirepressure balance apparatus are few.

[0019] 2. The operation of the tire pressure balance apparatus is verysimple.

[0020] 3. The driving safety and the car performance will be promoted.

[0021] 4. The car's life time will longer. While
